The inter-cooler pressure, for minimum work required, for a two stage reciprocating air compressor, is given by (where p1 = Intake pressure of air, p2 = Inter-cooler pressure and p3 = Delivery pressure of air)
A. $${{\text{p}}_2} = {{\text{p}}_1} \times {{\text{p}}_3}$$
B. $${{\text{p}}_2} = \frac{{{{\text{p}}_1}}}{{{{\text{p}}_3}}}$$
C. $${{\text{p}}_2} = \sqrt {{{\text{p}}_1} \times {{\text{p}}_2}} $$
D. $${{\text{p}}_2} = \frac{{{{\text{p}}_3}}}{{{{\text{p}}_1}}}$$
Answer: Option C
Solution (By Examveda Team)
The inter-cooler pressure, for minimum work required, for a two stage reciprocating air compressor, is given by $${{\text{p}}_2} = \sqrt {{{\text{p}}_1} \times {{\text{p}}_2}} .$$Where p1 = Intake pressure of air, p2 = Inter-cooler pressure and p3 = Delivery pressure of air.

Answer wrong p2=√(p1×p3)
p2 = sqrt(p1*p3).
